What you wrote is great but I do want to give you some tips.
1) Do you know what Subtle means? You need to know what words mean before you write it down. Subtle - especially of a change or distinction. Here is an example - It was a subtle of gray.
Other than that the text you wrote is amazing! Good Job! I guarantee you will get an A+! Plus you so deserve an A+!!!
Answer:
The sampling distribution of the mean will have no unit.
Explanation:
Given that:
P(B) = 0.62
P(C) = 0.71
pˆB = 0.70
pˆC = 0.75
The expression : pˆB−pˆC
Represents the difference in mean of the sample distribution :
The proportions pˆB = 0.70 and pˆC = 0.75 are obtained as (number of workers who purchased coffee / total number of workers). The ratio above due to division will have no units.
